X-ray production and their applications IN KANNADA MEDIUM VIDEO FOR DMLT AND PARAMEDICAL STUDENTS

What is X-ray...??
X-rays are a very energetic form of electromagnetic radiation that can be used to take images of the human body.

X-rays also have these properties:

• they have a very short wavelength (about the same size as the diameter of an atom.
• they cause ionisation (adding or removing electrons in atoms and molecules)
• they affect photographic film in the same way as visible light (turning it black)
• they are absorbed (stopped) by metal and bone.

X-Ray Production:

X-rays are produced due to sudden deceleration of fast-moving electrons when they collide and interact with the target anode. In this process of deceleration, more than 99% of the electron energy is converted into heat and less than 1% of energy is converted into x-rays.

X-rays are produced when electrons strike a metal target. The electrons are liberated from the heated filament and accelerated by a high voltage towards the metal target. The X-rays are produced when the electrons collide with the atoms and nuclei of the metal target.

Applications of X-Rays:

1)X-rays are used in industrial, medical, pure science research and X-ray crystallography etc.

2)X-rays are used to detect defects in radio valves. 

3) X-rays are used to detect cracks in structures. 

4)X-rays are used to analyses the structures of alloys and other composite bodies by diffraction of X-rays.

5) They are also used to study are structure of materials like rubber, cellulose, plastic, fibres etc.

6) X-rays can destroy abnormal internal tissues. 

7)X-rays are used in analysis of crystal structure and structure of complex organic molecule. 

8)They are also used in determining the atomic number and identification of various chemical elements. 

9)X-rays are used to detect fractures and formation of stones in human body. 

10)They are also being used for tumor treatment and for this purpose hard X-rays are used. 

11) X-rays are also used in X-ray crystallography for Laue method, Rotating crystal method, Powder method, etc.
